FASTENER.

Application filed November 2, 1917.

To all ywhom it may concern:

Be it known that. I, Furio S. CARR, a citizen of .the United States, and a resident of Newton, in the county of lizliddlesex, Commonwealth of Massachusetts, (whose post-office address is care of Carr Fastener Company, Cambridge, lvlassachusetts) have invented an Improvement .in Fasteners, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention pertains to improvements in fasteners. vention are to provide a stud and socket fastener in which the stud and socket are readily separable when tipped one relative to the other in one direction, and which is simple in construction, strong, positive in its action and of great durability.

Referring to the drawings, which show one illustrative embodiment of my invention:

Figure 1 is a front elevation of a preferred form of my invention;

Fig. 2 is a longitudinal section thereof, partly in elevation, on the line 2f-2 of Fig. 1';

l Fig. 3 is a transverse section on the line 3-3 of Fig. 2.

In the illustrative embodiment of my invention shown in the drawings, I have provided a stud 4 having a head 5 providing a neck 6 adapted to be engaged between a fixed jaw 7 and a. spring jaw 8 in such a way that when the lower portion of-the socket shown in Fig. 2 is moved outwardly relative to the socket, the spring jawS will ride over the shoulder provided by 5 ofthe stud, thereby permitting the opposite shoulder of the stud to slide outfrom under the fixed jaw 7. rlhe fixed jaw 7 is preferably, as shown, died forwardly from the intermediate plate') of the socket, while the spring 8 is preferably held in the casing 10 having bearing portions 11, 12 died forwardly therefrom and adapted torclosely Isurround and engage the head 5 of the stud t when stud and socket. are in interlocked relationship. The front plate or casing 10 13 projecting rearwardly therefrom and adapted to be clenched over a back plate 14 in the usual manner. The intermediate plate 9 or back plate .14 preferably combine to permit relative tipn Among the objects of the in the head- Specification of Letters Patent. Patented Sept. L, 'Lgfl..

ping movement of stud and socket inthe direction of the arrow shown in Fimf'l when sufficient force is exerted to spring the jaw 8 downwardly,` said plates being formed to prevent or limit substantial tippingvmovement of stud and socket in all other directions.

It will be understood that in some instances and for Some purposes it may be preferable to attach the main portion of the socket to that side of the fabric on which the body of the stud is located, thereby avoiding the necessity of perforating the fabric for passage cf the stud therethrough. It is unnecessary to illustrate this form of attachment, which is wellknown and which is shown in various co-pending applications.

Among the features of the invention which I wish to emphasize as advantageous, both when used independently of each other and particularly when used in combination with cach other, are included the striking forward of the. fixed jaw 7 from the plate 9 and the provision in this combination of the opposed spring jaw 8 and the support 11, 12 for the head of the stud The illustrated construction of the fixed jaw 7, which is quite independent of the front plate or casing 10, permits the full utilization of the plate 10 for the provision of the supporting surfaces 11, 12, while the combination of the jaw 7, spring jaw 8 and supporting surface 11,12 contribute greatly to the strength. of the structure, to its resistance to wear and to the rigidity with which the stud and socket are held together when engaged.

lVhile I have shown and described one embodiment of my invention, it is obvious that changes involving omission, alteration, substitution and reversal of parts, and eve-n changes in the mode of operation, may be made without departing from the scope of my invention, which is best defined in the following claims. f

Claims:

1. A stud and socket fastener comprising, in combination, 'a stud having a head and a neck; a socket having a fixedjaw for engagement with one side of said neck and a rcsilient jaw for thel opposite side of said neck. said socket also providing an extended bearing projected forwardly to support said head.

2. A stud and socket. fastener comprising, in combination, a stud having a head and a eey neck; a socket providing a plate having aA stud-receiving aperture therein and a portion thereof adjacent said aperture projecting forwardly to provide a fixed jaw for en gagement with one side of said neck, a sec ond plate forward of the first-named plate vand llaving'an extended portion thereof projecting forwardly to provide an extended bearing for the head of the stud.

in combination, a' headed stud, a'socket in- .'cludingfront and rear plates defining between ythem a jaw-receiving chamber, the

rear plate being apertured to admit the stud and the front plate adapted-to overlie lt-he head thereof, a springjaw in said chamber adapted to engage behind said head on one Side and an integral extension of said rear plate adapted to engage behind said head on the 'opposite side. 'y

4:. A stud and socket fastener comprising, in combination, a headed stud, a socket in- 3. A stud and socketfastener comprising,

eludng front and rear plates defining between thema jaw-receiving chamber, the rear plate being aperturedv to admit the stud and the front plate adapted tooverlie the head there-f?, a spring jaw in said chamber adapted to engage behind said head on one side and a rigid'jaw carried by said rear plate projecting in said chamber and adapted to engage behind said head onthe opposite side.

5. Astud and socket fastener comprising, in combination, a headed studfa socket having a jaw-receiving chamber and a fixed jaw and a resilient jaw 'presented to said stud within said chamber to engage behind the head on opposite sides thereof,the front wall of said chamber having an inwardly opening recess to receiveand support the head.

In testimony whereof, I have signed my naine to this specification.
